50% or 0.5 is the probability that the offspring will have a cleft chin.
Explanation:
Data given:
Cleft chin = dominant, genotype CC
one parent, heterozygous so genotype, Cc
other parent = no cleft chin, genotype is cc (recessive)
probability of child with cleft chin =?
The cross between the given genotype will be shown in punnet square:
C c
c Cc cc
c Cc cc
The results obtained from the cross shows that 50% chances of the progeny having cleft chin.
The phenotype ratio: cleft chin: no cleft chin
1:1
the genotype ratio of the progeny
heterozygous dominant : recessive homozygous
1:1
Because the skin sloughs off on a regular basis, the most superficial layer of the epidermis is primarily composed stratified squamous epithelium. The correct option is D.
<h3>What is stratified squamous epithelium?</h3>
Stratified squamous epithelia can be found in nearly every organ system that has direct contact with the outside environment, including the skin, respiratory, digestive, excretory, and reproductive systems. They also keep the body from drying out and losing water.
The most surface-level layer of the epidermis is composed principally of stratified squamous epithelium since the skin sluffing off on a regular basis.
Thus, the correct option is D.

Answer:
Mitosis and meiosis both involve duplication of a cell's dna content
<span>the area that would most likely experience the greatest amount of natural erosion is : the coastline
When the waves crashed the coastline it will started a process called abration, when the land is detoriorated over time due to its friction with thewave
The best method to prevene this is by planting mangroves near the coastline</span>

This type of collision is a <u>Inelastic collision </u>
Explanation:
We begin by finding the momentum of the initial train car;
Remember that momentum is given by the formulae mass (kg) * velocity (m/s)
Therefore;
Momentum = 6000 * 10
= 60,000 kg⋅m/s
The other car has zero momentum because;
4000 * 0
= 0
When the two train cars collide, the total momentum will be;
60,000 + 0 = 60,000
Therefore to find the velocity, well use the same formulae;
p = mv whereby;
p – momentum
m – mass
v – velocity
60,000 = (6000 + 4000) * v
v = 60,000 / 10,000
v = 6
= 6 m/s
This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.
